A peculiar pattern has emerged in the stream of anecdotal data we call the internet. Within a few weeks, four seemingly disconnected events formed a distinct cluster. First, a passenger on a flight to Thailand was filmed casually preparing gutkha (a popular form of chewing tobacco). Then, on its inauguration day, Bihar's brand-new Rajgir International Cricket Stadium was christened with the familiar red-brown splatter, an event that led one outlet to declare, Gutkha defaces Bihar’s brand-new Rajgir Cricket Stadium - ‘That’s the signature mark!’. This was followed by a viral photo of identical stains on Mumbai’s newly launched Metro Line 3, and a reminder that Kolkata’s iconic Howrah Bridge is being chemically corroded by the same substance.

The online response was immediate and predictable. The sentiment, aggregated across platforms, coalesced around a singular diagnosis: a national deficit of "civic sense." Commenters lamented a cultural failing, a lack of public decency, and a disregard for shared spaces. The man on the plane became a symbol of this supposed decay, with the debate centering on whether his actions were offensive only if he spat.

This is, by my analysis, a fundamental misinterpretation of the data. Focusing on the nebulous concept of "civic sense" is an error in diagnostics. It’s like analyzing a patient’s cough without ever asking what they’re smoking. The variable being measured is wrong. The recurring incidents aren't a signal of widespread moral failure; they are the predictable, statistically inevitable outcome of a product whose consumption cycle is inherently incompatible with public infrastructure.

The Flawed Metric of "Civic Sense"

The public discourse, which I treat as a qualitative data set, reveals a fixation on individual behavior. On the video of the man preparing gutkha mid-flight, one user argued, "If he’s not making unnecessary voices, not spitting, not disturbing others, minding his own business then you should mind your too." This sentiment was common. The act itself was deemed acceptable; only its potential consequence—spitting—was considered a breach of etiquette.

This is a fascinating, if flawed, line of reasoning. It isolates one data point from its inevitable conclusion. The consumption of chewing tobacco requires expectoration. It’s not an ancillary behavior; it's a core function of the product's use. To permit the preparation but condemn the spitting is to ignore the product's entire lifecycle. What if we're analyzing the user when we should be analyzing the product's inherent design flaw? Is it truly a failure of individual discipline, or is it a systemic failure to account for a product whose primary byproduct is corrosive waste?

The calls for public shaming, CCTV identification, and fines, while emotionally satisfying, are operationally inefficient. They propose a solution that requires constant, expensive surveillance to mitigate the damage of a low-cost, widely available product. It’s like trying to catch every drop of rain in a storm with a thimble. The scale of the problem dwarfs the proposed enforcement mechanism. This isn't a problem of a few bad actors; it’s a numbers game. With millions of users, the probability of public spitting approaches 100%.

Quantifying the Externality

The aesthetic argument—that the stains are ugly—is subjective. The structural argument, however, is not. Let's look at the Howrah Bridge in Kolkata. The structure has survived for over 80 years—82 years, to be precise, since its completion in 1943. It withstood Japanese bombing raids during World War II. This contrast is often highlighted online, with headlines proclaiming that Kolkata's Howrah Bridge survived World War bombs- but is losing to 'Gutkha spit'. Internet says, 'Ajay Devgn supremacy'. Yet, according to a 2013 report from Kolkata Port Trust engineers, it is being actively damaged by gutkha.

I've looked at hundreds of infrastructure maintenance reports, and the specificity of this chemical corrosion is what I find genuinely arresting. The acidic mixture of saliva, slaked lime, and areca nut creates a chemical reaction that corrodes the steel hangers at the base of the bridge. The measured thickness of the steel plates had been reduced by as much as 50% in some areas before protective fibreglass casings were installed. This is not about appearances. This is quantifiable, physical degradation of a critical piece of infrastructure.

This is a classic negative externality—a cost imposed on a third party who is not involved in the transaction. The transaction is between the gutkha seller and the consumer. The cost of cleaning stadiums, replacing metro panels, and repairing bridges is borne by the public. The current debate is like arguing about the etiquette of drivers in the 1970s without mentioning that their cars are running on leaded gasoline. For decades, the solution was seen as better car maintenance and more responsible driving. The real, effective solution was systemic: removing the lead from the fuel itself. The problem wasn't the driver; it was the product.

At what point does the cumulative, recurring cost of public infrastructure repair and sanitation outweigh the tax revenue and commerce generated by this product category? Has anyone run those numbers?

A Failure of Product, Not People

The persistent, viral outrage over gutkha stains is a symptom of a society treating a product design problem as a crisis of personal morality. We are stuck in a loop, debating the "civic sense" of millions while ignoring the inherent properties of the substance they are consuming. If a product's use cycle inevitably results in the degradation of public property, the most efficient solution isn't to launch a nationwide campaign to reform the character of every citizen. It's to re-evaluate the product itself. The calls to "ban gutkha," often dismissed as emotional, are, from a purely data-driven perspective, the most logical conclusion. The externality is simply too high.
